A multimeter can measure which trio?

• A. Voltage, resistance, and current
• B. Voltage and power only
• C. Current and frequency
• D. Resistance and capacitance

Answer: (A)

A multimeter is designed to measure three fundamental electrical quantities: voltage, current, and resistance. Voltage shows the electrical potential difference between two points, which you read by placing the meter’s probes across the component or circuit part you want to test. Current reveals how much charge is flowing through a path, which you measure by inserting the meter in series so all the current passes through it. Resistance indicates how much a component or path resists the flow of current, which you read with the circuit powered off and the probes across the component.

This combination—voltage, current, and resistance—is what a typical multimeter directly provides. While some meters can also measure other things like capacitance or frequency, those are not universal features, and power is usually calculated from voltage and current (P = VI) rather than measured directly.
